Minerals

Hardness Scale with Test Kit

Includes first nine minerals used in Mohs’ scale, plus a streak plate, glass plate, and nail. Packed in a sturdy, polystyrene tray with lid. Includes identification key. More.

Fluorescent Minerals Collection – Long and Shortwave

This study unit illustrates the response of certain minerals to ultraviolet radiation. Contains some minerals which only respond to shortwave radiation, others which only respond to long-wave radiation, and some respond to both, but with differing d... More.

Scale of Hardness Collection with Diamond

The traditional Mohs’ scale with a small diamond included. This set contains 10 numbered 1" (excluding the diamond) natural specimens in a compartmentalized container. More.

Scale of Hardness Collection

This collection is the traditional Mohs’ scale, which assigned a “hardness” to 10 key minerals with talc No. 1 (the softest) and diamond No. 10 (the hardest). The first nine minerals are included in this set. The 1" specimens are n... More.

Physical Properties of Minerals Collection

This kit familiarizes the student with the physical properties used to identify minerals. The following physical properties are represented: hardness, streak, color, luster, cleavage and fracture, specific gravity, tenacity, and magnetism. Included are ... More.

Luster Collection

Recognition of the kind and degree of luster of some minerals is an aid to identification. This collection provides examples of both metallic and nonmetallic types of luster. Contains 15 numbered 1-1/2" natural specimens in a compartmentalized t... More.

Streak Collection

Some minerals will demonstrate a colored streak on unglazed tile which gives a key to identification of that mineral. Examples of this property can be demonstrated with this collection. Contains eight numbered 1" natural specimens in a compartmental... More.

Fluorescence Experiment Kit

A complete and affordable experiment kit that explains and demonstrates the properties of fluorescence. When certain ordinary, dull-looking rocks are exposed to ultraviolet light, they will actually emit visible light in brilliant colors – thi... More.
